CoinGecko Historical

If these instructions are already present in the conversation from a slash or dollar invocation, follow them directly; do not invoke this skill again through a skill tool.

Open a validated ±1-day window around the requested date in Chromium.

Workflow

1. Require a CoinGecko coin ID and an ISO date (YYYY-MM-DD). Resolve a supplied name or symbol with cg search <term> -o json before continuing.

2. Build the URL with the portable helper:

   uv run <skill-dir>/scripts/build-url.py <coin-id> <date>
   

   Invalid IDs or calendar dates exit nonzero without opening a page.

1. Pass the returned URL to mcp__chrome-devtools__new_page with background: false.

2. Completion is ### 🌐 CoinGecko history opened — <coin-id> · <date> (±1 day) followed by the linked page URL. Do not use the macOS open command. Keep the helper's bare-URL stdout and validation errors undecorated.
